BYD Airbag/SRS Warning Light: What It Means and What To Do
What the airbag (SRS) warning light means on BYD models, and why you should never try to diagnose it yourself.
Safety and service note
What this means
The airbag fault warning light turns on when the ignition is switched on and should go off again within a few seconds if the airbag system is working properly. This warning light monitors the airbag ECU, collision sensors, the inflation device, the warning lights themselves, their connections, and the power supply.
What causes it
If the airbag warning light stays on, or turns on while driving, it means a fault has been detected somewhere in this monitored system -- the exact component cannot be identified from the dashboard alone.
What to do
Contact a BYD authorised dealer or service provider for vehicle inspection as soon as possible. Never attempt to inspect, test or work on the airbag/SRS system yourself -- this is a safety-critical system that can cause serious injury if handled incorrectly, and it must only be serviced by trained technicians with the correct safety procedures.
Important
Contact a BYD authorised dealer or service provider for vehicle inspection as soon as possible. Never attempt to inspect, test or work on the airbag/SRS system yourself.
Frequently asked questions
Is it normal for the airbag light to come on briefly at startup?
Yes -- it should turn on with the ignition and go off within a few seconds if the airbag system is working properly; that briefly on-then-off cycle is a normal self-check, not a fault.
What does it mean if the airbag light stays on?
It means the system has detected a fault somewhere in the airbag ECU, collision sensors, inflation device, warning lights, connections, or power supply -- contact a BYD authorised dealer or service provider as soon as possible.
Can I keep driving with the airbag light on?
You can drive to a service appointment, but do not delay -- an active airbag fault means the airbag system may not deploy correctly in a collision, so have it checked as soon as possible.
Is it safe to check the airbag system myself?
No. The airbag/SRS system is a safety-critical, high-energy system that can cause serious injury if handled incorrectly. Diagnosis and repair must only be done by an authorised BYD technician.
Does a stored airbag fault clear itself?
No -- a genuine fault needs to be diagnosed and cleared by a technician; it will not resolve on its own.
Does this apply to other BYD models, not just ATTO 2?
Yes -- the airbag warning light and its monitored components are described the same way across BYD's current EV and DM-i owner handbooks.
